Answer:
Step-by-step explanation:
We need a system of equations to help us solve this. One of the equations in the system is about the number of cultures bought, and the other one is about the money spent on the cultures. They are 2 very different things!
The #'s equation says that the number of cultures (c) plus the number of vials (v) totaled 57. The equation that puts that together is
c + v = 57
Now for the money part. Each culture costs $8, so the expression for that is 8c; each vial costs $1, so the expression for that is 1v; we know the amount of money spent in total was $106. The equation for that is
8c + 1v = 106
There's our system. 2 unknowns need 2 equations. Go back to the first one and solve it for either c or v. I'll solve for c, just because:
c = 57 - v. Now sub that value for c into the money equation:
8(57 - v) + v = 106 and
456 - 8v + v = 106 and
-7v = -350 so
v = 50. There are 50 vials of fruit flies. To find c, plug that into the first equation:
c + 50 = 57 so
c = 7.
f(x)=x^2-5 find f(7)
Answer:
44
Step-by-step explanation:
substitute the 7 into the equation for x
f(x) = [tex]x^{2}[/tex] - 5
f(7) = [tex]7^{2}[/tex] - 5
f(7) = 49 - 5
f(7) = 44
Answer:
f(7) = 44
Step-by-step explanation:
To evaluate the function f(x)=x^2-5 at x = 7, replace each instance of 'x' in this function by 7:
f(7) = 7^2 - 5 = 49 - 5 = 44
So: f(7) = 44

find the value of x and y, (5x-3y, 3x-y) = (16, 12)
Answer:
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>
Step-by-step explanation:
Another way to rewrite (5x-3y, 3x-y) = (16, 12),
5x - 3y = 16 -- (1)
3x - y = 12 -- (2)
Rewriting (1), y = -5/3x - 16/3 -- (1)'
Substituting (1)' into (2),
3x + 5/3x + 16/3 = 12
14/3x = 20/3
x = 10 / 7 -- (3)
Substituting (3) into (2),
3(10/7) - y = 12
30/7 - y = 12
-y = 54 / 7
y = - 54/7-- (4)
Therefore,
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

Answer:
This is the answer48 cm²
Answer:
A = 44 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
We require to find the missing segment of b₁
Using the tangent ratio in the right triangle
tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4}{adjacent}[/tex] = 1 , so
adjacent = 4
Then
b₁ = 4 + 8 + 2 = 14 , b₂ = 8 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 4 × (14 + 8) = 2 × 22 = 44 cm²
Why are 1997 pennies worth almost twenty dollars
Answer: Most 1997 pennies in circulated condition are only worth their face value of $0.01. These coins can only sell for a premium in uncirculated condition. The 1997 penny with no mint mark and the 1997 D penny are each worth around $0.30 in uncirculated condition with an MS 65 grade. unless you have an very rare 1997 penny thats then when it would become worth 20$

Answer:
Tree C
Step-by-step explanation:
each of the charts/tables/paragraphs are talking about a different tree.
Tree A started with 5 inches, as it says.
Tree B started with 3 inches, as you can see under the 0 months.
Tree C, at the month 0 mark, has a height of 10 inches, so it started with 10.
10>5 and 10>4, so Tree C is the biggest
The drama club is running a lemonade stand to raise money for its new production. A local grocery store
donated cans of lemonade and bottles of water. Cans of lemonade sell for $2.50 each and bottles of water
sell for $1.25 each. The club needs to raise at least $600 to cover the cost of renting costumes. The students
can accept a maximum of 460 cans and bottles.
Write a system of inequalities that can be used to represent this situation.
The club sells 144 cans of lemonade. What is the least number of bottles of water that must be sold to cover
the cost of renting costumes? Justify your answer.
Answer:
Part A
x + y ≤ 460...(1)
2.5·x + 1.25·y ≥ 600...(2)
Part B
The number of bottles of water the student must sell ≥ 192 bottles of water
Step-by-step explanation:
The given parameters are;
The selling price of each can of lemonade = $2.50
The selling price of each bottle of water = $1.25
The amount of money the club needs to raise = $600
The maximum number of cans and bottles the students can accept = 460
Part A
Let 'x' represent the number of cans of lemonade the students accept, and let 'y' represent the number of bottles the student accept, the system of inequalities that can be used to represent the situation can be presented as follows;
x + y ≤ 460...(1)
2.5·x + 1.25·y ≥ 600...(2)
Part B
The number of cans of lemonade the club sells, x = 144
The number of bottles of water the student must sell to cover the cost of costumes, 'y', is given from the second inequality as follows;
2.5 × 144 + 1.25·y ≥ 600
1.25·y ≥ 600 - 2.5 × 144 = 240
1.25·y ≥ 240
y ≥ 240/1.25 = 192
y ≥ 192
The number of bottles of water the student must sell = 192 bottles of water

O The function that is represented by the equation y=-10x+6 has a steeper slope, and the function that is
represented by the equation Y-36 = 8(x-4) has a greater y-intercept.
O The function that is represented by the equation Y-36 = 8(x-4) has a steeper slope, and the function that is
represented by the equation Y = -10x+6 has a greater y-intercept.
O The function that is represented by the equation Y-36 = 8(x-4) has a steeper slope and a greater y-intercept.
9514 1404 393
Answer:
(a) The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept
Step-by-step explanation:
If we take the "steepness" of the slope to be the absolute value of the slope, then the line y=-10x +6 has a slope with a steepness of 10.
The line y -36 - 8(x -4) has a slope with a steepness of 8, so the first line is steeper.
The line y=-10x+6 has a y-intercept of 6. The line y-36 =8(x -4) has a y-intercept of 4, so the first line has a higher y-intercept.
The appropriate description of the two lines is ...
The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

O A. 4
O B. -9
O C. 15
O D. 59
Answer:
B. -9
Step-by-step explanation:
X² + 14x +45=0
(x+9)(x+5)=0
x = -9 or x = -5
x = -9 is the answer
Answer:
B. -9
Step-by-step explanation:
X^2 + 14x +45=0
Factor
What two numbers multiply to 45 and add to 14
5*9 = 45
5+9 = 14
(x+5)(x+9) = 0
Using the zero product property
x+5 =0 x+9=0
x+5-5 =0-5 x+9-9 = 0-9
x = -5 x=-9

What is the length of the diagonal of a 3 by 6 rectangle
Answer:
The diagonal is 6.7082 ≈ 6.71
Step-by-step explanation:
Let the diagonal be x :
To find the diagonal of a 3 by 6 rectangle
We can use the Pythagorean Theorem:
[tex]x^{2} = 3^{2} + 6^{2}[/tex]
⇒ [tex]x^{2} = 9 +36[/tex]
⇒ [tex]x^{2} = 45[/tex]
⇒ [tex]x=\sqrt{45}[/tex]
∴ [tex]x =6.7082[/tex] ≈ [tex]6.71[/tex] (corrected to 2 d.p.)
If AGHJ ~ ALMK, with a scale factor of 5:6,
find the perimeter of AGHJ.
Answer:
35
Step-by-step explanation:
Perimeter of LMK = 14 + 11 + 17
Perimeter of LMK = 42
Perimeter GHJ/ Perimeter LMK = 5/6
Perimeter GHJ / 42 = 5/ 6 Cross Multiply
6*Perimeter GHJ = 42 * 5
6*Perimeter GHJ = 210 Divide by 6
Perimeter GHJ = 210/6
Perimeter GHJ = 35
The area of the triangle is 42 square inches. Determine the length of the height, by applying the formula of area of triangle.
Answer:
The answer is height=7
Step-by-step explanation:
Formula needed for this problem is Area= Base times Height divided by 2.
The first step to solving this problem is to do the exact opposite of this formula. since we already know the area we will multiply that by two to get 84. Then 84 will be divided by 12 to get 7. If anything confuses you on this problem please feel free to ask!

The width, w , of a rectangle is 4 less than 6 times the length, r that would find the area.
Answer:
Width = w
Length = 4w + 6
Area = 130 in2
Area = W X L = 130
So, w X (4w + 6) = 130
4w2 + 6w = 130 by distributing
-130 -130
4w2 + 6w - 130 = 0
Step-by-step explanation:
Answer:
Area = 6L² - 4L
Step-by-step explanation:
Let length be L
Given Width, w is 4 less than 6 times length :
That is ,
6 times length = 6 L
4 less than 6 times length means = 6L - 4
Therefore Length = L
Width = 6L - 4
Area = Length x Width
= L x ( 6L - 4)
= 6L² - 4L
